It is a bit complicated to say what the movie is really about, as there are two possible plots here. Anyway, it is about a young guy who stays alone in the middle of the big water. And he needs to decide what is really useful in his life. What I really like is the scene when his father tells him he cannot be a guy of many faiths (Hinduism, Christianity and Islam at the same time) and the kid wonders innocently why. Cos he learned something from all of them and he feels OK.
